the formation of novel and known compounds, such as porphyrinic meso-OH and N-oxide derivatives. This work demonstrates how the extraordinary structural stability of the porphyrin macrocycle redirects the reactivity patterns of classic ring-expansion reactions, which outlines some limits of the methods to convert a pyrrole in porphyrins into a nonpyrrolic buildingblock.
